DESCRIPTION Available in high power packages, the BTA/ BTB40-41 series is suitable for general purpose AC power switching. They can be used as an ON/ OFF function in applications such as static relays, heating regulation, water heaters, induction motor starting circuits, welding equipment... or for phase control operation in high power motor speed controllers, soft start circuits... Thanks to their clip assembly technique, they provide a superior performance in surge current handling capabilities. By using an internal ceramic pad, the BTA series provides voltage insulated tab (rated at 2500 V RMS) complying with UL standards (File ref.: E81734). ABSOLUTE MAXIMUM RATINGS
